"I came to browse the Internet and build robots. And I am done browsing the Internet". Many different approaches, principles and directions to constructing robots with detailed building instructions and pictures.
Робота Икозейтър е конструиран с идеята да може лесно да се променя зъбната му предавка. На видеото може да наблюдавате един начин за смяна на предавката му, като се извади гредата и се разменят зъбните колела на мотора и верижното колело. За предавки с различен размер зъбни колела се иска промяна в дължината на веригата или броя зъбни колела.
Football with robots could be quite fun. Football with LEGO Mindstorms robots is one of the popular categories for competitions with LEGO Mindstorms Robots.
As we are already off the season we decided to look back at the competition. First, we will take a look at the working solution for FIRST LEGO League 2017 Manhole Cover. This was generally accepted as one of the most difficult missions during the competition. We've built a single attachment to accomplish it.
(we are releasing the video without explanations and will add the explanations later)
Should the robot be with a Front Wheel Drive or a Rear Wheel Drive to make it more precise? The answer is - front wheel will probably give you better results, but the wheel drive is not the most important thing. In this video tutorial on the LEGO Mindstorms Robots, we will do a few experiments to discuss the influence of the wheel drive on the precision of the movement.
You could use the LEGO Steel Balls as a third wheel on the robot. It is a caster wheel. But this is steel and as we know from basic existence on this planet, where there is steel there is also rust. The steel ball could get quite rusty and this could have an influence on the behaviour of the robot
DIfferent wheels and tires will result in different behaviour of the robot. That is actually pretty common sense. The real question is what is the influence. Would the robot make smaller deviations if it has smaller wheels or it will make larger deviations? The tires could also be quite dirty or brand new. Or the wheels could be attached in different ways.
The balance of the construction of the robot has a great influence on how it will move. This is especially true if you would like to move in a straight line. If the robot is slightly heavier on the right it will move to the right. Here we have two robots - a Five Minute robot and a Box Robot and we will discuss the differences in the constructions and why the box robot is much better than the Five Minute even though it is using the same parts.
Present the details
What is a single, and what is two degrees of freedom
Let's attach the ball storing pipe to the FTC robot. In previous tutorials, I've shown you the complete robot, but for this, I've removed the pipe and will show you how to attach it.
Take the hacksaw, the drill and let's cut the pipe.
In this tutorial, we record an example of how to cut the pipe to the desired length with a hacksaw. Cutting with a hacksaw is very common during FIRST Technical Challenge Preparation
